Development of cloud‐based power system operational data management system

Integration of Internet of Things and cloud computing: a systematic survey

“…Cloud computing proposes a valuable solution for managing IoT services and tackling applications and service composition [53]. Consequently, it is obvious that the combination of IoT and cloud computing has been reached its maximum in recent years [54,55]. This trend has reflected on several surveys [56][57][58], and consequently products [59].…”

Development of a quasi‐real‐time distribution voltage monitoring system

“…For decrypting the ciphertext to plaintext, the other key, i.e. the private key, is used [12]. Due to the higher algorithmic complexity of the RSA algorithm, hardware implementation of the RSA algorithm is difficult.…”

“…The plaintext, M and ciphertext, C are interrelated as C = M e mod n and M = C d mod n , where d and e are the values provided by the two users located at encryption and decryption end. The public key (PU = { e , n }) and private key (PR = { d , n }) can be is generated from two prime numbers ( a and b ) by following the given steps [12]. (i) Determine n : = a * b and x : = ( a −1)*( b −1). (ii) e : = Any prime number between 1 and x.…”

“…Therefore the private key, which is a function of d and n , will have greater security than a public key, which is a function of e and n . From the obtained value of PR (or PU), C (or M ) can be computed by the given pseudocode [11, 12] (see Fig. 4).…”

“…A compressed, encrypted algorithm is proposed in [11] for power system operational data where the dataset is compressed by using differential binary encoding algorithm (DBEA) and is encrypted by using the Rivest–Shamir–Adleman (RSA) algorithm. The compressed, encrypted data management algorithm, smart DBEA encryption (S‐DBEAE), is developed in [12] and a PC‐based setup is developed for real‐time testing. In S‐DBEAE, the compressed information is also encrypted by using the RSA algorithm and few identity characters are included to identify a particular dataset according to some fields.…”
